Spatiotemporal mapping of alloy mesostructure dynamics via multimodal coherent X-ray diffraction imaging Open
Understanding mesoscale structural dynamics of precipitation-strengthened alloys is essential for optimizing the mechanical performances of these alloys. Herein, we establish a multimodal coherent X-ray diffraction imaging framework for sp…

Three-Dimensional Nanoscale Imaging of SiO2 Nanofiller in Styrene-Butadiene Rubber with High-Resolution and High-Sensitivity Ptychographic X-ray Computed Tomography Open
SiO2 aggregates in styrene-butadiene rubber (SBR) were observed using ptychographic X-ray computed tomography (PXCT). The rubber composites were illuminated with X-rays focused by total reflection focusing mirrors, and the ptychographic di…

The false beat signal of a high-speed X-ray imaging detector for synchrotron radiation experiments and its elimination with a synchronized CITIUS detector Open
Recent advances in high-speed X-ray imaging detectors for synchrotron radiation experiments have enabled frame rates to exceed 10 kframes/s. The frame rates are getting closer to the revolution frequencies of the large-scale storage rings,…

Bragg coherent diffraction imaging with the CITIUS charge-integrating detector Open
The CITIUS detector is a next-generation high-speed X-ray imaging detector. It has integrating-type pixels and is designed to show a consistent linear response at a frame rate of 17.4 kHz, which results in a saturation count rate of over 3…

Advancement of X-ray radiography using microfocus X-ray source in conjunction with amplitude grating and SOI pixel detector, SOPHIAS Open
We show how to improve microfocus X-ray radiography by using the SOPHIAS silicon-on-insulator pixel detector in conjunction with an amplitude grating. Single-exposure multi-energy absorption and differential phase contrast imaging was perf…
